Different length for both...but I don't remember what length that is. I've since returned back to a stock sized damper.

Yeah.... didn't order it from SLP... ordered it from summit... and they dont have any info on their site for it... and its not here yet...
so i dont have the sheet they probably send with it...
Plan on putting it on as soon as it shows up... didnt want to have to run to the parts store later if I can do it now while I'm already running errands..
